SHEARS AND SClSSORS SHARPENER.

SPECIFICATION forming part of Letters Patent No. 492,810, dated March'7, 1893. Application filed June 30, 1892. Serial No. 438,541- (Nomodel.)

To all whom it may concern:,

Beit known that we, ALEXANDER KING, residing at- Painesville, Lakecounty, and FRANK F. KING, residing at Cleveland,in the county ofOuyahoga, State of Ohio, have invented certain new and usefulImprovements in Shears and Scissors Sharpeners; and we do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same.

Our invention relates to improvements in shears and scissors-Sharpeners,and more especially to the means employed for holding the blades of theshears or scissors against lateral slipping or displacement insharpening the same, and whereby the edge of the blades to be sharpenedmay always be ground to the same bevel; and it consists in certainfeatures of construction and in combination of partshereinafterdescribed and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective of ashears and scissorssharpener embodying our invention. Fig. 2 is alongitudinal section of the same, showing a bladcof a pair of shears inposition. Fig. 3 is an end elevation looking in the direction of thearrow, Fig. 1.

Referring to the drawings, A represents a block, preferably of wood.Block A is recessed at the top, as at a, with the recess extendinglengthwise from end to end of the block, as shown, and open at the ends,as at a. The blade-holder is composed of a plate B of spring metal, theplate being bent centrally and transversely, as at b, forming twomembers, B B with the ends, I) b of the plate terminating a trifle aboveblock A so that recess a in the block is adapted to receive a file O ofsuch thickness that the cutting surface O of the file will be located ina plane slightly above the top of the side-walls of said recess. MemberB of the plate, at each side of block A, has lateral members, bextending in a direction away from member B and being enlargeddownwardly outside of block A, as at b, and rigidly secured to thelatter.

In sharpening a blade of a shears or scissors, the same is interposedbetween members B B of the blade-holder, and then drawn back and forthacross the cutting surface of the file. Member B of the blade-holderconstitutes aspring that is adapted to act in the direction against theadjacent side of the blade to besharpened'and firmly hold the bladeagainst member B, with the edge to be ground in proper position upon thecutting surface of the file. The blade-holder is set at the desiredangle to the supporting-block whereby the blade to be sharpened is heldat a corresponding angle to the cutting surface of the file; hence theedge of the blade is ground to the desired bevel and it will be observedthat by our improved device the blade is always ground to the samebevel, a feature of no inconsiderable importance.

What we claim is l. The combination with a block grooved or recessed onone face to receive-a file, of a blade holder spanning the groove orrecess, said holder comprisingarigid memberandaspring adapted to holdthe blade to be sharpened against the rigid member when drawn throughit, substantially as set forth.

2. The combination with a block, A, recessed at the top, 0:, with therecess extending lengthwise-of the block and open at the ends, andadapted to receive a file, of a blade-holdersecured to the aforesaidblock and comprising a rigid member, B, and a spring, as at B integralwith said rigid member and adapted to hold the blade to be sharpenedagainst said rigid member of the blade-holder, substantially as setforth.

In testimony whereof we sign this specification, in the presence ofwitnesses, this 11th day of June, 1892.
